Late-Time Dark Matter Oscillations and the Core-Cusp Problem
James M. Cline, Guillermo Gambini, Samuel D. McDermott +1
The core-cusp problem persists as an unresolved tension between the predictions of CDM cosmology and observations of dark matter (DM) profiles in dwarf spheroidal and other gala…
Beyond the Standard Model Explanations of GW190521
Jeremy Sakstein, Djuna Croon, Samuel D. McDermott +2
The LIGO/Virgo collaboration has recently announced the detection of a heavy binary black hole merger, with component masses that cannot be explained by standard stellar structure…
Missing in Action: New Physics and the Black Hole Mass Gap
Djuna Croon, Samuel D. McDermott, Jeremy Sakstein
We demonstrate the power of the black hole mass gap as a novel probe of fundamental physics. New light particles that couple to the Standard Model can act as an additional source o…
Missing in Axion: where are XENON1T's big black holes?
Djuna Croon, Samuel D. McDermott, Jeremy Sakstein
We pioneer the black hole mass gap as a powerful new tool for constraining new particles. A new particle that couples to the Standard Model---such as an axion---acts as an addition…
Supernova Muons: New Constraints on Z' Bosons, Axions, and ALPs
Djuna Croon, Gilly Elor, Rebecca K. Leane +1
New light particles produced in supernovae can lead to additional energy loss and a consequent deficit in neutrino production in conflict with the neutrinos observed from Supernova…
Constraints on Primordial Black Holes From Big Bang Nucleosynthesis Revisited
Celeste Keith, Dan Hooper, Nikita Blinov +1
As space expands, the energy density in black holes increases relative to that of radiation, providing us with motivation to consider scenarios in which the early universe containe…
